I have a full box of these transistors in case anyone needs them.

$0.15 ea (min.100 pcs) or
$0.1 ea (min. 500 pcs).

Shipping would be flat @$10 worldwide (up to 500 pcs).

PM me if interested

Thanks for looking!

Save 100 for me, along with 6 upa68h.... what else audio do you have (bjt)

Out of curiosity, are the noise specs similar to the 2240? If so I’ll take a couple hundred.

I'm not entirely sure about that. Comparing their datasheets, there are some slight differences in their noise specs. I called it a mini version of the 2SC2240 based on the Toshiba databook. Apart from the noise, I believe they share similar characteristics.Thanks

Ok

Its not 2sc2240 in diferent packing, its more like 2sc2713 THT version. those were available 3 years ago at 0.10/each and i bough a thousand, but its real pain in the *** to work with it(match to pairs) so 2SC2459 is more DIY friendly at least.

 

[bango]

Yeah, you're right, it looks like the 2SC2713 has the exact same specs as the 2SC2459 (except for the power rating, of course).

The Toshiba databook also mentions it as the super mini version (SMD) of the 2SC2240 (for general purpose application).



@K-amps
Sorry Arif, A1349 & C3381 all gone!
So, this is all that’s left:

-A970GR & C2240GR $1.5/pair
-A1015GR & C1815GR $0.4/pair
-A949Y & C2229Y $0.7/pair
-A1306B-Y & C3298B-Y $3.5/pair​

Out of curiosity, how do the A1306/C3298 compare to devices like the A1859/C4883 or A1837/C4793? I have A1930/C5171 but from what I have heard have poor SOA specs.

My apologies, I’m still learning to compare SOA charts, but they look to be similar to the A1859/C4883 with of course slightly lower IC spec and 100 MHz vs 120 MHz.
This is all stemming from the Wolverine build, I’m going to be purchasing some A1859/C4883 for the amps I’m building, but would really like to have some nice, quick drivers on hand for future use.

If my thinking is correct and you agree I’d be in for several, 30-40 pair.

I’d say all of them are suitable as excellent driver transistors. The final result will be more dependent on the overall quality of the circuit. The A1930/C5171 does have poor SOA specs, but other specs are actually better than the others.
for applications with not-too-high voltages, it’s still a good choice.IMO

Yeah, you're right, they are quite similar in SOA. But the A1306/C3298 both have an Ft 100 MHz, while the A1859/C4883 has 60/120 MHz.

UP!
